When you’re trying to connect Power BI to Dynamics CRM by entering Dynamics CRM OData Service URL, you may receive an obscure message “Parameter validation failed. Please make sure all parameters are valid.”
What Power BI is trying to tell you is that the license assigned to you is the Power BI freebie and not the Power BI Pro goodness.
Be a pro, go back to O365 Admin Portal and assign the correct license. Don’t have it? Free trial is available and it’s only $9.99 per month for many hours of entertainment trying to build a Klein
funnel bottle out of your sales data.
